Barack Obama sworn-in for second term as US president

US President Barack Obama is officially sworn-in for his second four-year term
in the White House.

4:26PM GMT 20 Jan 2013

Barack Obama was sworn in to shoulder the power and burden of the US presidency for a second term on Sunday, launching two days of inauguration ceremonies.

Using a bible belonging to First Lady Michelle Obama's grandmother, Democrat Obama, 51, swore to faithfully execute the office of president at a low-key ceremony in the Blue Room of the White House, to comply with the US Constitution, which dictates his first term ends at midday on January 20.

In a tradition honoured when that date falls on a Sunday, Obama will repeat the oath in a public ceremony Monday, and deliver his inaugural address to Americans, and the watching world, outside the US Capitol.
